Animals once again proved to be more intelligent than previously thought:
Behavioral surveys of the roughly 370 gorillas in U.S. zoos showed 48 variations in how individual groups of the apes make signals, use tools and seek comfort, said Tara Stoinski of Zoo Atlanta and the Dian Fossey Gorilla Fund International.Categories: gorillas | apes | zoos | animal behavior
"What became very obvious is there is a very distinct pattern of similarities and differences between groups," Stoinski said.
That suggests the gorillas pass along the different traits socially, not genetically, which is a hallmark of culture.
